"METHOD or HANGING GATES, 8w.

Specification ofLetters Patent Nol 1 0,928, dated May 16, 1854.

To all whom it may concern Be it known that I, N. W. CILLEY, ofNottingham township, Rockingham county, New Hampshire, have invented anImprovement in Sliding Gates, Doors, &c., of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, making part of this specification, in whichFigure 1, is a plan; Fig. 2, an elevation; and Fig. 3, a verticalsection taken at the line A, a, of Fig. 2.

The same letters indicate like parts in all the figures.

My invention relates to a method of suspending gates, doors, sceneframes, and other like structures which are now generally made to workon slidesor on ways, with the view to reduce the amount of powerrequired to work them, and avoid, in a great measure, the wear and tear.to which such structures have heretofore been exposed. And my inventionconsists in suspending the gate or other movable structure to one end ofa lever, or pair of levers, the other end of which slides in verticalways or the equivalent thereof, when this is combined with another leveror pair of levers jointed to the first at the middle of their length,the

one end of the said latter lever turning on a fixed fulcrum while itsother end is connected by a joint link with a standard attached to thegate or other structure to be moved,

by means of which arrangement the gate or other structure is sustainedand maintained in the same or nearly the same line, and can be movedback and forth with only so much friction as is due to the turningjoints which sustain the weight. The levers performing the doublefunction of joints for the motion, and braces to sustain the weight.

In the accompanying drawings a represents a gate of open frame workwhich, near the lower edge, and at, or near, the middle of its length isconnected by a fulcrum pin to a lever I), made intwo parts, one on eachside, the better to support the gate without strain. The upper end ofthis lever is adapted to slide between ways 0, 0, attached to the upperpart of the post d', on one side of the gate way. Another lever e. ofequal length with the first, is pivoted to the first at the middle oftheir length, as at t f, and the lower end of this lever e, turns .56

on a fixed fulcrum in a fixed standard 9,

opposite the post d, the other or upper end being connected by a jointlink it, with a vertical standard on the inner end of the gate,

and of such height relative to the length of the lever e that during theentire motion of the gate, the link vibrates to an equal extent aboveand below a line parallel with the line of motion of the gate. Thislever e,

can be double, one part on each side of the and is free to move back andforth turning the levers on their several joint pins, their upper endsmoving up and down, the one in its ways and the other with its jointlink. When the gate is shut, the two levers are at right angles to eachother, and both diagonal to the line of motion of the gate, the'twolevers acting as reversed braces to sustain the gate, and when the gateis entirely open the two levers assume just the reverse of the positionthey occupy when the gate is shut. As the only wearing points are theconnections at the several joint pins, the liability to derangement andwear will be much less than when working in slides or on ways.

Instead of having the upper end of one pair of levers working in aslide, it may be maintained in its vertical movement by a joint linklike the other, except that the joint link must be connected at one endwith a fixed post. Wherever, as in working the scene frames of theaters,the levers on each side would be in the way, they can all be locatedabove, and connected with the upper instead of the lower edge.

I deem it unnecessary to enumerate the various structures to which myinvention can be applied with advantage, as it will be obvious that allcumbersome frame work or structures, which have to be moved back andforth in a straight, or nearly straight, line like a sliding door orgate, can be suspended and operated on my improved plan.

I am aware that a system of connecting levers or links have been used,called the parallel motion for connecting the end' a vibrating circularmotion, and therefore I other and to the gate or other structure and donot Wish to be understood as making to the fixed Work, substantially asspecified claim to any such device; and for the purpose set forth.

What Iclaim as my invention and desire 1 N. W. CILLEY.
